Who's child is this?

When Mac and I got home, I told him to come with me so I could change.  I went in our room but he didn't follow.

I finally found him in his room, taking the new bag of socks and putting them into his sock drawer.  Not only that, but I was throwing something away later and found that after he put away his new socks, he put the bag into the kitchen trash!

Keep in mind that nobody told him the socks where his, much less that they needed to be put away.  I'm pretty sure that's his mom and not me.
